7 Claims.

; This invention relates to improvements in combined closet bowl and tank structures, and more particularly has to do with improved means for securing the flush tank upon the shelf of the closet bowl.

r An object of. the invention is to provide improved securing means of'a simple, efficient nature that will be readily accessibleand can be more easily adjusted in connecting the tank to the closet bowl shelf.

Another object of the invention is to provide improved means for securing'the tank to the bowl shelf, which will avoid the necessity of providing I an opening in the bottom wall of the hollow shelf and the provisionof packing at this point, and which will be positioned wholly within the hollow shelf.

The invention, with other objects and advantages thereof, and the particular construction, combinations and arrangements of parts com prising the same, will be understood from the hereinafter contained detailed description, when considered in connection with the accompanying drawings, forming part hereof and-illustrating two embodiments of the invention. r

In the drawings: I Figure 1 isa vertical central section through adjoining parts of awater closet bowl and'tank structure constructed in accordance with the present invention; Figs. 2 and 3 are fragmentary perspective views of gaskets employed respectively between the flush valve structure and tank outlet, and between the tank outlet and bowl inlet; Y v

Fig.4 is a detailedsectional view on the line 4-4 of Figure 1, looking downwardly;

Fig. 5 is a vertical transverse section on the line 55 of Figure 1, looking in the direction of the arrows;

Fig. 6 is a horizontal section on the line 6-6 of Figure l;

'7'is a vertical section from front to rear through the joint and adjoining closet bowl and tank parts of. a modified construction, and

. Fig. 8 is a section on the line 88 of Figure 7.

While two specific embodiments of the invention are illustrated in the drawings, it will of course be understood" that minor changes and modifications maybe made in the particular and side walls 4 and '5,the latter being con- 7 constructions shown, and the invention may be tinuous with the rear wall 6 of the downleg l of the syphon, and the wall I of the syphon forming the bottom Wall of the shelf. The top wall 2 of the shelf is provided with an opening 8. Forwardly of this opening, the shelf has a transverse rib 9', and to the rear of the opening at either side are raised portions H].

H designates the flush tank supported on the shelf on the transverse rib 9 and raised portions It with the opening I I in its bottom aligned with the opening 8 of. the shelf. Within the tank is a conventional flush valve structure I2 having the threaded portion [3 projecting below the bottom of the tank. [4 designates a rubber gasket interposed between a flange I5 on the valve structure and the bottom wall of the tank, and I6 is a gasket between the top Wall 2 of the shelf and the bottom of the tank. The valve structure I2 is held in place by a threaded tubular coupling member or sleeve I! at the exterior of the tank engaging the threaded portion l3 of the valve structure. The coupling member, which is open at its sides, is shown as comprising a threaded sleeve portion IS with spaced depending arms l9 joined at their lower ends by a transversely extending'centrally apertured plate portion 20.

Means for securing the flush tank II to the hollow shelf is provided comprising a bolt 2| and nut 22 cooperating with the coupling member l1 and with an anchoring wall portion. 23 located within the hollow shelf, said wall portion being joined to the side walls 3, 4, 5, of the shelf and extending horizontally in spaced relation with the top and bottom walls of the shelf below the coupling member IT. The anchoring wall portion may be and preferably is provided, as shown, with water passages 23. The bolt has an elongated rectangular shaped head 24 and is detachably engaged with the anchoring wall by passing the head 24 of the bolt through a correspondingly shaped slot 25 in the anchoring wall. The bolt extends upwardly through the aperture in the transverse plate portion 20, and the nut 22 fits against the upper side thereof. The nut is provided at the top with a transverse slot 26 for engagement by a screw driver in adjusting the same. Lugs 21 are provided on the under face of the anchoring Wall 23 to prevent turning of the bolt. As will be understood, in assembling the parts, the boltZl is first engaged with the anchoring wall 23, the coupling member I! connected with the valve structure is threaded over the shank of the bolt, and the nut 22 is then put on the bolt and turned up to securely clamp the parts together, the adjustment of the nut being readily accomplished from the interior of the tank II.

It will be noted that by the special construction and arrangement of parts hereinbefore set forth means of a simple, efiicient nature is provided for securing the tank to the shelf of the closet bowl. The securing means is readily accessible in assembling and for adjustment, and the necessity for providing an opening in the bottom wall of the hollow shelf with accompanying packing,

- tachably engage the wall portion within the shelf,

and a nut engaging said screw member within .the shelf and fitting against the upper side of is avoided.

In the modified construction illustrated inFigures 7 and 8 of the drawings, the means for securing the tank to the shelf of the closet bowl is similar to that hereinbefore described to the extent that it provides for more easy access thereto but in this construction the fastening bolt is engaged with the bottom Wall of a shelf instead ofan anchoring wall located within the same. In Figures '7 and 8, 28 designates the Water closet bowl provided with a hollow shelf 29. 30 is the tank, 31 the valve structure, 32 the tubular couplingmember connected with the valve structure, and 33and 34 the securing nut and bolt, the latter in this instance having laterally projecting lugs 35 engaging slot 36 in the bottom wall of the shelf tohold the, bolt against rotation during the adjustment of the nut, which, as in the con- 'struction illustrated in Figures 1 to 6, is provided with a slot 3?; in the top thereof for engagement by a tool to turn and thereby lock the assembled structure. 1
